Application filed January 28, 1922. serial No. 532,508.

To all whom itmury concern:

Be it known that I, Ronnnr W. WIEDER- WAX, a citizen of the UnitedStates, residing This invention relates to heating devicesit for thecooling systems of motor vehicles.

Inthe present invention, I provide a casing adapted to fit the front andrear of a radiator having shutters to control the flow of air throughthe radiator. A burner is 15 arranged within the casing at the frontand.

a passage 18 provided for air to support combustion. The products ofcombustion pass ofi through a vertical passage commumeating with ahorizontal passage at the top 2c of the casing which is arrangedadjacent a ortion of the air passage to preheat the air. hence, theproducts of combustion pass through the radiator.

object of the present invention 1s the as provision of a heatercomprising a casing which may be closed when the burner is lighted forheating purposes and opened when the vehicle is running.

A further object of the invention is the provision of. means forsupplying preheated air to the burner.

A further object is the provision of means for preheating the air by theproducts of combustion and then passing the products of combustionthrough the radiator.

In the accompanying drawings, 1 have shown one embodiment of theinvention. In this showing:

Figures 10 is a horizontal sectional-view on line 10-10 of Figure 8,and,

Figure 11 is a detail sectional view on line '11-11 of Figure 4.

. Referring to the drawings, the reference numeral 1 designatesgenerally a motor vehicle provided with a radiator 2. The radiatorcommunicates -with the lower water chamber 3, and an upper chamber 4,each of I which is connected to the cooling jacket of e the engme (notshown), in the usual manner.

The heater forming the subject matter of the present invention comprisesa front casing 5 which is arranged in front of the radiator andsupported in any suitable manner. As shown, the casing is provided withside walls 6, the ends of which are flanged, as at 7. A strip 8 issecured to the side wall ad j acent the flange, and this strip isprovided with a pair of flanges 9 and 10, arrangedsubstantially'parallel to and spaced from the flange 7.

The front wall adjacent the radiator is formed of alternate stationaryand movable plates producing a shutter efiect. As shown, the stationaryplates 11 are secured between the flanges 9 and by suitable fasteningelements 12. The movable plates 13 are arranged between each pair ofstationary plates, and the ends of these movable plates are offset, asat 14, and received between the flanges 7 and 9. These plates arearranged slightly ofi-set from the vertical plane of the stationaryplates, as shown in igure 2. The movable plates are connected to a rod15,- having a rack 16 formed adja cent its upper end. This rack mesheswith a pinion 17, carried by a' horizontal rod 18, extending through theradiator and provided with an operating handle 19 in frontof the casing.

The rear of the radiator is closed by a. casing or plate which islikewise provided with alternate stationary and movable sections. Thisrear plate consists of stationary sections 20 and movable sections 21.The movable sections 21 are provided with od-set ends 22, which arereceived in spaces formed by plates 23 and 24 of vertical strips 25,secured to the rear of the radiator. These movable sections aresimilarly connected by Nil vided with slots 29 to permit the plates tomove upwardly.

Beneath the bottom of the radiator, the

front is provided with a solid wall 30 and a bottom 31. The wall 32extends upwardly from the bottom of the front casing to the lower levelof the radiator. At the top of the radiator, the casing is provided withan inclined wall 33 having a plurality of openings 34. Beneath theinclined wall, there is provided an air passage 35, formed by horizontalwalls 36 and 37, and vertical walls 38 at the front and rear. Thispassage communicates with openings 34, by means of an inclined passage39. Adjacent the side of the passage 35, there is provided an air duct40, extending to a point beneath the upper end of the Wall 32. At theopposite side of the casing, a vertical passage 41 is provided. Thispassage forms a flue for the escape of products of com bustion, andcommunicates with a space 42, at the top of the casing above the airpassage 35. The walls of the air passage may be provided with openin42.-

Adjacent the bottom, there is provided a horizontal wall 43, extendingfrom one side of' the casing to the vertical wall formin the inner sideof passage 41. The end of the air duct passes through this wall. The

horizontal wall 43 and the bottom form a burner easing which is adaptedto receive a burner casing 44. The burner casing comprises a fuel tank45, and a burner tank 46, separated from each other by a perforated wall47. The fuel tank is provided with a filling opening, closed by a cap48. The burner tank is provided with a filling 49 of suitable fibrousmaterial to retard the flow of liquid fuel. A burner 50 is arranged onthe top of this tank, the burner comprising a base plate having openings51 for the passage of air spaced from the top of the burner tank by legs52. A wick 53 is mounted in a wick chamber 54, and is provided with theusual control member 55. The bottom of the wick extends through the topof the burner tank. as shown in Figure 4 of the drawings. When theburner is in position, the top of the burner co-operates with thehorizontal wall 43 to form a transverse air passage 56 to deliver airfrom the air duct 38 to the burner. The side wall adjacent the burner isprovided with a door 57 hinged thereto, as at 58, which may be opened toinsert and remove the burner and fuel tank.

This door is provided with a slot 59 for the eaneao passage of theburner control member 55, and is further provided with a transparentwindow 60 to permit inspection of the flame. The door may also beprovided with a suitable catch 61.

Beneath the radiator, the walls 30 and 32 of the front casing areprovided with alined openings inwhich a sleeve 62 is arranged Thestarting crank 63 of the engine is adapted to be passed through thissleeve.

The operation of the device is as follows:

When the engine is running, or in warm Weather, the shaft 18 is revolvedthrough handle 19 or 28 to move the plates 13 and 21 upwardly behind theplates 11 and 20 and thus permit passage of air through the radiator forthepurpose of cooling the fluid in the cooling system of the motor. Whenthe engine is standing. in cold weather and there is danger of freezing,the burner 50 is lighted and the products of combustion pass up throughthe vertical chamber or flue 41 to the space 42. From the space 42, thegases pass around the tubes of'the radiator, heating the water or otherfluid and preventing it from freezing. The flow of the products ofcombustion creates a draught in the horizontal passage 56, causing airto enter openings 34 and pass through passages 35 and 39 to the air duct40. The incoming air in the passage 35 is heated by the products ofcombustion in the space 42. It will be noted that this space is open inthe front of the horizontal passage 35, which permits the products ofcombustion to flow on all sides {2; of the air passage 35 before passingthrough the radiator.

The openings 42' are provided to permit escape of some of the incomingair through the radiator when the amount of air supplied is more than isnecessary to support combustion. The air passing through openings 42joins the products of combustion and passes through the radiator. Theproducts of combustion in the flue 41 heat the space between the frontwall of the front casing and the front of the radiator, and this heat isconveyed by radiation through the radiator, thus heating the entireradiator. The space 42'being in free communication with the radiator,except at one side where the flue 41 is provided, any back drafts escapedownwardly into the space removed and replaced by opening the door It isto be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.
